To all whom it may concern:

Be it known that I, GUSTAV KATZENSTEIN, a citizen-of the Empire ofGermany, residing at Berlin, Germany, have invented certain new anduseful Improvements in Apparatus for Washing and Purifying Wool andCotton Fibers and other Fibrous Material, of which the following is aspecification.

This invention relates to an improved apparatus for washing andpurifying wool and. cotton fibers and other fibrous material; and

'the object of the invention is to provide an apparatus in which thepurifying-solution is intimately mixed with the fibrous material and thecleaning of the fibers accomplished I without the formation ofknottedparticles,

so that theipaterial is purified in a more thorough manner than ispossible in appliances heretofore in use.

. The invention consists of an apparatus for I Washing and cleaningfibrous materiaL'comprising a stationary vessel provided with an archedcover of special construction and an agitator for imparting centrifugalmotion to the mixture of fiber and purifyingsolution,

and, further, of certain details of construction,

which will be f ully described hereinafter and finally pointed out inthe claims.

--In the accompanying drawings, Figure 1 represents a vertical centralsection of the apparatus for purifying wool and cotton fibers.

Fig. 2 is a plan View of the cover and attached funnel in invertedposit-ion. Fig. 3 is a top View of the centrifugal wheel 6, Fig. 1. Fig.4 is a top view of the annular trough 10, Fig. 1, and adjacent parts.Fig. 5 isa vertical central section of a modified form of construc tionof the apparatus. Fig. 6 is a plan View of a portion of Fig. 5, and Fig.7 is a detail top view of the steam turbine wheel.

Similar letters and figures of reference indicate corresponding parts. 7

In the apparatus shown in Figs. 1 to 4 a vessel b, made of circular orparabolic shape, I

' by means of an annular arched cover 0., which is attached to thecircumference of the vessel band which is formed with a centralinwardly-extending spout f. -In bearings of the standard a is arranged ahollow rotary shaft (1, to the upper end of which, inside the vesin Fig.g

To the mouth of the internal spout f of the cover a is attached afunnelg, the dischargetube of which extends-intothe mputhof the centrifugalwheel e and supports at its in .terior a hollow distributing-cone t,which communicates by tubes 70, attached to the tube h, with theinterior of the vessel b. This distributing-cone serves, furthermore, asa cover for the upper' end of the hollow shaft (1.

l A tube l,.forming a continuation'of the hollow shaft- (1, connects thelower end of the hollow cone with the same. i

sel b, is keyeda centrifugal wheel e, which-is shown in section in Fig.1 and in plan view Around the funnel g is arranged a wire net m, so thatno part of the product can pass into the pipe k. At the lower part ofthe hollow. shaft (1 are arranged a number ofsmall' discharge-nozzles1", below which an annular trough pis arranged concentrically to, thehollow shaft (1, as shown in Figs. 1 and 4.

The interior of the cover 0 is provided with radial or spiralguide-vanes s, as shown in Figs. land 2. The vessel b'is providedwithguide vanes or blades w,-which form a continuation in downwarddirection'of the curved vanes s. 1 1 y 1 The operation of this apparatusis asfol-' lows The centrifugal wheel 6 is set into quick rotary motionby means of any suitable power transmission a, and water is conducted atthe same time through the supply-pipe y into,

the funnel g,while the fibrous materialis introduced at f and isconductedto the wheele through the funnel g. The centrifugal wheel 6throws the fibrous material,which is conducted to the same in thedirection of ar I rows n, owing to' the m's ma imparted to the materialalong the vanes or ribs w s, so that it is returned along the tubularcentral portion f of the cover into the funnel g. In this manner acontinuous rapid circulation. of the water and fibrousmaterial takesplace, whereby a reliable and quick cleaning of the fibers is produced,so that the latter remain always in a loose flaky condition-withoutformingknotted particles. The separated impurities,which are usuallyspecifically lighter than water, are collected near the net wt and aredrawn.,with the water, through the net m, the pipe is, through thghollow distributingtoo cone 2', the hollow shaft cl, and small nozzles1' into the trough 19. From the latter the water is conducted oifthrough the pipe 0. For the purpose of sterilizing the fibrous materialsteam can be conducted through the pipe as into the vessel 1 In theconstruction shown in Figs. 5to 7 the vessel 1) is made of conicalshape, while the cover 0 is provided with guide vanes or ribs sin thesame manner as in the apparatus shown in Fig. 1. At the center of thevessel is likewise arranged a hollow shaft (1, which turns in step andneck bearings 8 and 9. The shaft (1 is provided with stirrer-arms 10 andcarries at its lower end a so-called Seguer turbine wheel 11,whichisshown in detail plan view in Fig. 7 The upper end of the hollow shaft isconnected with a steam-supply pipe 12.

v The upper part 13 of the vessel 1) is enlarged mitted at f into theinterior of the vessel.

and provided with an annular chamber 14,

which serves for conducting 01f the muddy water. A sieve is attached tothe vessel at the opening into the annular chamber 14,

. purities pass to the outlet-pipe. The vessel 1) can be drained througha pipe 15, which is connected to the bottom of the same. The operationof this apparatus is almost exactly the same as that shown in Fig. 1.The water used for cleaning the fibrous material is ad- The turbinewheel 11 is set in quick rotation by the steam emitted through the same,so that the stirrer-arms. 10 are quickly rotated in the vessel 1). Thesteam produces simultaneously the sterilization of the fibrousmaterialand an intense motion of the solution.

' By the conical shape of the vessel 12" is proso as to bemoved inoutward direction, and

so on, it being kept in continuous agitation and circulation. The motionof the centrifugal wheel e or turbine wheel 11 can also be accomplishedin any other preferred manner.

For removing the fibrous material from the apparatus the cover isremoved, together with the funnel or tilted, while in Fig. 5 the coveris simply lifted-off. If this is not desired, the fibers may instead bedrawn 0% through a suitable pipe at the bottom of the vessel.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. An apparatus for washing and cleaning fibrousmaterial, which consists of a stationary vessel provided with an archedcover,a rotary agitator for imparting centrifugal motion to the washingliquid, and radial vanes or ribs at the under side of the cover forreturning the solution back toward the center of the vessel,substantially as set forth.

2. An apparatus for washing and cleaning fibrous material, consisting ofa stationary vessel, an arched coverhavinga central downwardly-extendingspout, radial vanes at the under side of the cover, a rotary motor forimparting centrifugal motion to the washing liquid, means for agitatingthe solution, and means for drawing off the washing-water, substantiallyas set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
